WebSep 24, 2024 · Think of CNF as a chain of conjunctions (ANDs) that join chains of disjunctions (ORs) which join propositions or their negations. As a helpful mnemonic, CNF is conjunctions of disjunctions. For example, the following is in CNF: $(p \vee q) \wedge s \wedge (\neg a \vee b \vee \neg c) \wedge t \wedge \neg w$ Webthe sentence (A∧B ∧¬C) ∨(¬A∧C) ∨(B ∧¬C) is in DNF. (a) Any propositional logic sentence is logically equivalent to the assertion that some possible world in which it would be true is in fact the case. From this observation, prove that any sentence can be written in DNF. ... is similar to the algorithm for conversion to CNF.) (c ...
